Summary
Quartz sand is a hard, wear-resisting, stable chemical property of silicate minerals, the main mineral composition is SiO2, quartz sand color is milky white, or colorless translucent, a multi edge type ball of white crystal, hardness, brittle cleavage, conchoidal fracture, oily luster, density is 2.65, bulk density (1-20 1.6), 20-200 head is 1.5, the chemical, thermal and mechanical properties has obvious differences to, insoluble in acid, slightly soluble in KOH solution, melting point 1750 DEG C.
Quartz sand application
Quartz sand is a unique physical and chemical properties, making it occupies a pivotal position in the aviation, aerospace, electronics, machinery, and today, with the rapid development of IT industry, especially in the inner molecular chain structure, crystal shape and lattice changes, so that it has high temperature resistance, thermal expansion coefficient is small, high insulation, corrosion resistance, piezo electric effect, resonance effect and the unique optical properties, is playing a more and more important role in many high-tech products.
Fine quartz sand can be used as abrasive, such as grinding glass:
Glass: flat glass, float glass, glass (glass jar, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and anti ray special glass as the main raw material.
Second, ceramics and refractory materials: embryo material and porcelain glaze, kiln with high silica brick, ordinary brick and silicon carbide and other raw materials.
Three, metallurgy: silicon metal, ferrosilicon alloy and silicon Aluminum Alloy and other raw materials or additives, flux
Four, construction: concrete, cementitious materials, road materials, artificial marble, cement physical performance test materials (cement standard sand)
